An MCP server that rewrites SQL queries at the AST level to prevent PII/PHI exposure.

## Why This Exists

AI agents write SQL. They also hallucinate column names, ignore access controls, and cheerfully SELECT * from tables full of personal data. This server sits between the agent and your PostgreSQL database, rewriting every query so hidden columns return type-preserving placeholders instead of real values. The agent gets useful results; your users keep their privacy.

## Quick Start

### 1. Create an allowlist

Generate a scaffold from your database schema:

```bash
# Install the CLI (skip if using uvx or Docker below)
pip install sanitized-db-mcp

sanitized-db-mcp generate-allowlist --database-url postgresql://user:pass@host:5432/mydb > allowlist.yaml
```

Edit the YAML to expose only the columns agents should see (see [Generating an Allowlist](#generating-an-allowlist) below).

### 2. Run the server

Pick one of the four methods below and add the config to your `.mcp.json`.

#### Method 1: uvx (recommended — zero install)

`uvx` runs the package in an isolated environment with no permanent installation and no dependency conflicts. Unlike pip, there is nothing to install or manage. Unlike Docker, there are no volume mounts or path mappings to configure.

```json
{
  "sanitized-db": {
    "type": "stdio",
    "command": "uvx",
    "args": ["sanitized-db-mcp"],
    "env": {
      "ALLOWLIST_PATH": "./allowlist.yaml",
      "DATABASE_URL": "postgresql://user:pass@host:5432/mydb"
    }
  }
}
```

No install needed. `uvx` downloads and runs the package in…
